PSW Universal

The PSW Universal Pump signal converter is used for connecting speed-controlled high-efficiency pumps to a controller without a corresponding output. Due to its flexible adjustment possibilities, almost any pump can be connected. Thus, when replacing the pump, speed control can be enabled without replacing the controller. The PSW Universal offers a total of 80 different signal combinations between bursts, leading-edge and trailing-edge phase cutting, PWM, 0-10 V, 0-20 mA, 4-20 mA and their inverted variations. It is additionally equipped with an L’ output that renders an external power supply to the pump unneccessary.
